BRIDGE LINE

This function generates a B-spline curve bridging two selected lines. The generated bridge line and the line selected at the first time are in the same part. The program displays a Select Line dialog box as illustrated in Figure 5.1.20 and prompts the user to select two lines. It should be noted that when choosing lines, the point close to the mouse clicking position is bridge point, i.e. B-spline curve.

There are three options available:

SELECT LINE

 

This is the default option.  The user may select lines from the screen without selecting this option.

 

NODES/POINTS

 

This option allows the user to define the line by selecting nodes or points on the screen.  The program will display an INPUT COORDINATES dialog box to prompt the user to select nodes or points to define the line. The last point is the bridge point of this line.

 

REJECT LAST

This option is used to reject the last selected line or defined line. 

 

Figure 5.1.21 illustrates the original lines and the generated bridge line.
